Thanks for voting and commenting. I certainly did see and use cables by the trail that lead to the arch (April 2010). I did not look to see if there were any cables or steps to climb the arch itself, if that is what you are talking about.

Sorry - I did not look close enough at your picture. East of Corona Arch itself there is a buttress that has a series of small toeholds cut into it that can be used to ascend the buttress and the top of Corona Arch itself. These toeholds have with them cable holders but no cables when we were there. Without the cables it is steep and has a couple of very exposed places. A fall would be fatal in a couple. My 12 year old son declined to try (I was tempted but thought better of forcing him to try it). If the missing cables were there, he would have tried it.
